T all whom it may concern.-

Be it known that 1, ROBERT S. MartinsoN, a citizen of the United States, and a resident of Manila, in the Philippine Islands, have invented certain new and useful Inn provernents 'in Gil Presses, of which the following is a specification.

My invention is an improvement in oil presses, and has for its object to provide a press of the character specified, by means of which the material from which the oil is pressed may be fed continuously between moving elements which compress the same to express the oil and which finally deliver the-pomace at the opposite end of the machine.

In the drawings:

Figure 1 is a side view of the improved press;

Figure 2 is an enlarged detail of one end, looking at the opposite side from Figure 1;

Figure 3 is an end view;

Figure 4 is'a side view of one of the outermost links,

Figure 5 is a top plan view of one embodi ment of pressing chain.

Figure 6 is aview similar to Figure 4 of another embodiment;

Figure 7 is a side view of one of the links.

Figure 8 is a fragmentary detail of a portion of the'upper chain, and

Figure 9 is a vertical sectional view showing the means for supporting, guiding and driving the inner chains.

In the present embodiment of the invention a suitable frame is provided, consisting of spaced side frames 1 which are suitably connected, and each frame has at each end a pair of upper and lower bearings 2 and 3. The bearings of one side frame register with those of the other, and shafts d and 5 are journaled' in the bearings.

Each shaft carries a drum or roller, the shafts 4 carrying drums 6 while the shaft .5 carries drums 7. Endless chains are supported on the drums of the corresponding shafts, and the said chains are constructed as shown in Figure 5. Each chain is made up of a series of sets of links, the links of each set being arranged alongside each other, with the alternate links extending at one end beyond the intermediate links, and with the intermediate links extending beyond the ends of the alternate links at the other ends of the links. The lower chain, namely, that supported upon the drums T, s channel shaped in cross section as shown in F igure This lower chain is made up, as before stated, of a series of sets of links 8 and 10.

The links 8 of each set are arranged alongside each other as shown in Figure 4-, and a link 10 is arranged at the outer side of each set of the links 8. Each link 10 has an extension 11 on one face, which extends above the plane of the chain to form the side walls of the channel. The ends of the sets of links interengage as shown in Figure 8, and are pivoted together in such manner that each set may swing with respect to the other set, forming thus a flexible endless chain.

A plate 8 is secured to the upper face of each set of links 8, the plate being of a length to extend between the extensions 11, and each plate has a series of openings as shown, the under side of each plate being also grooved transversely of the set, the grooves furnishing channels for the expi'e ssed oil. The links 10 have openings 11 registering with the ends of the grooves through which the oil may flow.

The upper chain, namely, that supported by the drums t, is constructed in the same manner as the lower chain, being formed of links 12 arranged in the same manner as the links 8 and 1.0, but the links 12 of the sets are abutted closely against each other, while there is an opening between the links 8 of the lower chain to permit the passage of the oil as it is expressed.

The aggregate width of the upper chain is such that it will fit between the extensions 11 of the lower chain, that is, the lower run of the upper chain will move between the side walls of the channel of the lower chain on the upper run of the lower chain. The opposite runs of each chain are supported intermediate their ends by another chain consisting of rollers 13 which are connected by links 141- to form an endless chain.

Referring to Figure 8. it will be noticed that the rollers have their ends reduced to engage openings in the links, and these chains are supported by oblong frames 15 which are of a width such that when the chains are on the frames they will engage the upper and lower runs of the chains supported by the drums 6 and 7 and will hold the adjacent runs of the two chains last named in contact. These frames or girders 15 are connected at their ends and held in rigid spaced relation by means of bolts 16 whi h are passed upwardly through the two frames and are engaged by nuts 17 above. the uppermost frame or girder.

Rollers 18 are provided for supporting the lower run of the lower chain, and the said rollers are journaled on longitudinally extending plates 19 in the side frames 1. Thelower run of the lower chain runs upon these rollers. The chains are driven by means of a pulley 20 connected by a belt with a suit able source of power, the said pulley being upon a shaft 21 which is journaled in the frame 1 above the uppermost chain and near one of the drums 6.

Bevel gearing 22 connects the shaft 21 with a vertical shaft 23 journaled in bearings on the adjacent side frame, and this shaft 23 has worms 2 1 which engage worm wheels 25 on the adjacent drums 6 and T.

It will be obvious that when the pulley 20 is'driven the shafts i and ,5 will also be driven to move the chains. Suitable feeding mechanism, indicated at 26, is provided for feeding the material to be pressed. This feeding means is shown as arranged at that end of the frame adjacent to the shaft 23 and, referring to Figure 1, it will be noted that the girders 15 are so arranged that the upper and lower chains are spaced apart on their adjacent runs at the feed end, and converge toward the other end of the said runs. The co-operating runs of the upper and lower chains are similarly arranged, gradually converging away from the feeding mechanism 26 toward the opposite end, and they only move in contact near the opposite end, and near the point they again begin to separate. The material fed between the converging runs of the up per and lower chains will be pressed, the pressure gradually increasing, and the expressed oil may pass out through the openings between the links of the lowermost chain, being collected by suitable means at this point. The pomace is delivered at the opposite end.

The chains 1314e are supported by drums 80. These drums are shaped to hold the chains vin the proper relation with respect the chains with the lower run of one chain and the upper run of the other chain contacting throughout a part of their travel, the lower chain having openings through it for the expressed oil and having upstanding flanges at its side edges, the upper chain moving between the flanges, means for supporting the said ad acent runs of the chains to cause them to gradually move toward each other from one end of the adjacent runs to the other, the lower chain consistlng of sets of links arranged side by side and pivoted to other sets at their ends, and a plate connecting each set of links, the upper chain being formed from sets of links, the links of each set being alongside each other and rigidly connected, the'alternate links extending beyond the intermediate links at oneend .of each set of links and the intermediate links extending beyond the alternate links at the other end of the set.

2. A press comprising a pair ofendless chains, means for supporting and moving the chains with the lower run of one chain and the upper run of the other chain contacting throughout a part of thelr travel the lower chain having openings through it for the expressed oil and having upstanding flanges at its side edges, the upper chain moving between the flanges, means for supporting the said adjacent runs of the chains to cause them to gradually move toward each other from one end of the adjacent runs to the other.
